Perakia sp. Fig. 4A Remarks.- We tentatively identified this species to be near to P. borneensis Willemse, 1936. This cryptic grasshopper was found on tree branches in the dipterocarp forest. The brown and elongated habitus of the grasshopper enables it to camouflage on branches. Interestingly, they were only encountered after the rain, perhaps suggesting that it is a canopy species, brought down to the understory by the rainfall. We identified our species based on the generic key by Willemse (1956) . We only have females and can only identify the species name tentatively. Identification was based mainly on color patterns.
